Okay, Lilo's legs may have looked a little soft yesterday but maybe it was just bad lighting 'cause girlfriend looked HOT in her Forever 21 mini dress last night all dolled up for a party at the Betty Ford Center.

The pleather booties weren't Lindsay's usual Rick Owens or Alexander Wang platforms but still ... she's making do with what she has and if it's Hot Topic and Aldo well then she's damn well gonna turn it into the best look she can!

Or maybe this was a dress her dad Michael brought for her during his visit? It's so Long Island!
